Troubleshooting
Symptom
Possible Cause
The engine won’t
start (Petrol)
• Is the ignition switch in the “ON” position?
• Is the fuel shut-off valve on?
• Are you using fresh, clean fuel? If the fuel is old, change
it. Use a fuel stabilizer if you keep fuel longer than 30
days.
• Is the spark plug clean? If the spark plug is dirty or
cracked, change it. If it’s oily, leave it out, hold a rag over
the plug hole and pull the recoil cord several times to
blow out any oil in the cylinder, then wipe off the plug
and reinsert it.
• Is there sufficient oil? Check the engine oil level and if
necessary top up to the correct level.
• Is there dirt in the carburettor? Undo the bolt holding the
float chamber to the carburettor, empty out any fuel and
clean the inside using fresh, clean petrol. Remove the jet
in the bottom of the carburettor and clean it. Refit the jet
and the float chamber.
• Is the pull start stuck or has more resistance? Check the
drum for blockages.
• Is the hopper securing bolt tight. If the lower bolt on the
hopper is not tightened then the safety cutout will be in
operation and the engine won’t start.

• If you press the start button on the mulcher and don’t
feel or hear a click of the button, then this typically
means that the mulcher isn’t receiving power.
• Is the plug connected to a power outlet?
